7HZ x Crinacle Zero:2 - Elevating Audio Excellence
7HZ Legacy Continues:
Building upon the global success of models like the Salnotes Zero, Dioko, and Timeless, 7HZ has solidified its reputation as a leading manufacturer of high-performance IEMs. The 7HZ x Crinacle Zero:2 represents a continuation of this legacy, promising not just innovation but an enriched community experience.
The Historic Collaboration:
The collaboration between 7HZ and Crinacle, marked by the original Zero, has made history in the budget IEM market. Crinacle, renowned for transforming the audio market with his frequency graph database, brings his expertise to refine the Zero:2. This updated model, a testament to their combined efforts, aims for the pinnacle of tonal balance and performance.
Balanced Upgrade with Enhanced Bass:
While the original Zero boasted an exemplary tonal balance, the Zero:2 introduces a 3dB boost in low frequencies. This enhancement doesn't compromise the existing balance but rather injects life into the sound, delivering a more powerful and engaging bass presence. The midrange, too, sees improvement in body and warmth, ensuring instrument and vocal frequencies are richer without sacrificing clarity.
The Power of the 10mm Dynamic Driver:
At the heart of the Zero:2's sonic prowess is a newly developed 10mm dual cavity dynamic driver. Featuring an upgraded PU+Metal composite diaphragm, this driver ensures a more responsive experience with faster diaphragm movement. The result is a blend of harder-hitting bass and precise note articulation, noticeable across the expanded frequency range of 10Hz to 20kHz.
Revamped Cable for Uncompromised Transmission:
Complementing the enhanced sound experience is the Zero:2's upgraded custom cable. Crafted from high-purity oxygen-free copper with silver plating, the coaxial structure ensures optimal audio transmission. Woven with 140.06 and 250.06 winding, the cable not only reinforces durability but allows for customization, empowering users to tailor their listening experience.

Let customers speak for us
Very quick and satisfying deliveries along with a wide range of products
Absolutely loved the soundstage and neutral bright tuning of this iem.
Best IEM for beginners. It helps to know what music taste matches to you.
These are great, every element of a song is well balanced. However, that balance is a double-edged sword, as it lacks bass. So, if you're looking for a strong base signature, you might want to choose something else or use an equalizer, which is what i'm doing.
This is a solid cable, which delivers stunning sound. I use this cable to connect my Hifiman EF400 to Fiio K15. This is a major upgrade to the sound (as compared to the two standalone).
I bought Cadenza as my first IEMs, before buying these I researched a lot about every kind in this budget I could go for, I streched and bought these as something which sounds, harmonious, smooth and comfortable for long sessions, even then the details and the sound still puts me in awe beating any earbuds and in ear sound system I have ever tried.
One of the best IEM.
EarAcoustic STA-Hi End Series IEM is too warmform me which is my sound signature. Beryllium driver tuned so fantastic. When was received this never go off from my ears to 4 hrs. I have so many brands and so many chifi IEMs used but this EarAcoustic STA-Hi End Series IEM is totally blowned me away. That's why this EarAcoustic STA-Hi End Series IEM is highly recommended. Thanks once againMr Pritam Ji for suggesting me so wonderful IEM in audio library collection.
The product came with all the accessories it should have, the box wasn't damaged at all and delivery was quick. It only took 2 days to be delivered and came with good enough packaging.
Overall, Very satisfied by theaudiostore. While this was my first time buying from them, It definitely won't be the last.
When I was a kid, somewhere around 2005–2007, I was gifted a Sony cassette Walkman. I was too young to care about model numbers or sound signatures. I just knew that pressing play felt important. That Walkman is gone now. Probably sacrificed to the great black hole where old chargers, socks, and childhood joy go to die. But the want never left.
So years later, I did what any emotionally stable adult does. I bought a Walkman again. This time, the Sony NW-A306. And no, this is not nostalgia cosplay. This is something else.
-> A Small Device With Strong Opinions:
The NW-A306 looks like a cute mini smartphone that went on a digital detox retreat. No camera. No speaker. No SIM. No “bro just one notification”. It exists only for music and has zero interest in your productivity apps or reels.
Physically, it feels solid and intentional. Buttons still exist. Sony clearly assumes you might listen to music without staring at a screen like it owes you money.
-> Android, But With Discipline:
It runs Android 14 and yes, streaming apps work. YouTube, YouTube Music, Spotify, Apple Music, Tidal, ... etc all fine. But here’s the thing, you can choose how modern you want it to be.
With Google services running, I casually listened for about 6 to 7 hours and still stayed under 60 percent battery usage. That’s respectable. Disable Google services and background nonsense, and suddenly the battery life becomes “arre yeh toh chale hi ja raha hai” level good.
Sony didn’t brute-force anything. This device feels tuned, not overpowered.
-> Sound - Sony Being Sony:
Let’s clear this upfront. Walkman is the legacy on which the iPod later thrived. Apple polished the idea. Sony invented the feeling.
And yes, it is Sony, so bass exists. No question about that.
The bass here is not the shaadi DJ type that enters before the song does. It is controlled, confident, and supportive. With KZ ZAS and Sony XM4s, the sound is clean, warm when needed, detailed when it matters, and never tiring.
As a USB DAC, this thing is frankly ridiculous for its size. Plug it into a PC and it behaves like a serious audio device pretending to be small for fun. Stable, clean, no tantrums.
This is not five-minute wow sound. This is “ab bas ek album aur” sound.
-> Local Music and the Joy of Making Things Difficult:
Now comes the part streaming apps will not like.
Yes, we have everything. Spotify, Apple Music, Tidal, Amazon, Qobuz, YouTube. Music is everywhere. And somehow, nothing sticks.
Algorithms keep suggesting. You keep skipping. Half the time you don’t even remember what you listened to two hours ago. Music becomes vibe. Background. White noise with feelings.
Owning music changes behaviour.
Ripping CDs into FLAC, fixing metadata, web scraping album art, organizing albums. This is effort. And effort creates attention. You listen to albums. You read lyrics. You notice production. You sit still.
Sony Music Center on Windows actually helps instead of testing your patience. Metadata, album art, even 12-tone analysis. Organizing music feels intentional, not like punishment for liking files.
The NW-A306 makes music feel yours. Not rented. Not borrowed. Yours.
Ironically, it uses modern tech to make things slightly complicated on purpose, so listening becomes simple again.
-> So Why Does This Exist?
The NW-A306 is not trying to replace your phone. It is reminding you why music once deserved its own device.
It is focused. It is disciplined. It does not beg for attention. And that is rare now.
If you treat music as something to truly listen to and not just something playing while you scroll, this Walkman makes complete sense. Emotionally. Practically. Logically.
Also, it feels really good to own your music again. Like, irrationally good.
Some loops are worth closing.
i was scared what if i will get scammed, or will the put stone in the box ,
but nothing happened like that, best unboxing experience, do take video, as its mentioned in the package either,
